I have to tell another story, taht could give some hint to the one trying to trace the problem.: I have a similar configuration, using a sarge with 2.4.26 , but i do not use shaping. The firewall is an old portable, with only 12 MB Ram. This morning i generated a quite large [460 MB] file on the gateway >From the other machine in my lan 0a win2k ws] I activated two ssh session int the gateway. then from the gateway i sent to the win2kWS (that run a sftp server) the file, using sftp. While transferring the file, that occurred at near full speed i was unable to connect to any host outside my lan. It was not a problem oif bandwidth, sinche the outside connetion was unused, and i was able to start other ssh connections between the two machine, without any problem. When from the gateway i tried to ping the host at the other end of isdn link i got only 1 packet on 23 with a delay of 11744 milliseconds ! So it is imilar to your problem: when one of the links is hogged, even the other ones, do not work. Note that when pinging the packets were sent and came back from the remote host ok [i could see the light on TA] and seem that is the gateway to miss such packets !!!!
